Varies directly basically means a multiple of
y = kx
where "k" is the constant of variation. You must solve for this first using the given information.
8 = 42k
8/42 = k
0.19= k
Equation: y = 0.19x
when x = 126
y = 0.19(126)
y = 24
Answer:
c³ + cd³ + 3c²d + 3cd²
Step-by-step explanation:
(c+d)^3 is worded as <em>c plus d quantity cubed</em> which doesn't mean you cube everything inside. It means you multiply the quantity by itself 3 times.
(c+d)(c+d)(c+d)
<em>You can only multiply 2 at a time so do the first two then the result and the third one.</em>
<em>Distribute everything in one quantity to the other so </em><em>c*c = c^2 and c*d = cd</em>
= (c^2 + 2cd + d^2)(c+d)
= c^3 + c^2d + 2c^2d + 2cd^2 + cd^2 + cd^3
<em>Combine like terms</em>
= c³ + 3c²d + 3cd² + cd³
